Embodiment
In the scope of exemplary embodiment framework of the ADSL2 of regulation in the G.992.3 draft standard version (revising 6) in December, 2008; But the invention is not restricted to this concrete environment, but use in adjustable other framework of the network parameter between the network terminal and network equipment therein.Certainly, present embodiment also is applied to such as the ADSL2+ of regulation in G.992.5 and the DSL standard of other type the VDSL G.993.2.
Expression is according to the system of this embodiment in Fig. 1.DSL modulator-demodulator 1 is arranged in the home network 5 that also is known as home network.The DSL modulator-demodulator can be independent device or be integrated in DSL gateway or the client device (CPE).The DSL modulator-demodulator is connected to wide area network (WAN).Particularly, WAN is the internet.In order to enter the Internet, modulator-demodulator 1 is connected to digital subscriber line access multiplexer device 2 (DSLAM).DSLAM is provided with the DSL parameter in the modulator-demodulator.DSLAM also is known as central station (CO) hereinafter.The DSLAM owner is the access network provider 3 (ANP) that network insertion is provided to the DSL modulator-demodulator.Internet service provider 4 (ISP) provides the internet to insert to the DSL modulator-demodulator.
In Fig. 2, further represented DSL modulator-demodulator according to present embodiment.The whole module of not representing the known modulator-demodulator of DSL itself.Fig. 2 representes the module for the maximally related modulator-demodulator of present embodiment.Particularly, this modulator-demodulator comprises DSL configuration module 11, and it adapts to according to hereinafter and comes setup of modulator-demodulator with further describing.Modulator-demodulator also comprises user interface 12, makes the end user to select and designated parameter according to present embodiment.Modulator-demodulator also comprises the processor 15 that adapts to the algorithm of carrying out embodiment.Modulator-demodulator also comprise with the interface 14 of local network and with the interface 13 of WAN.
For configuration parameter, DSL configuration module 11 obtains the parameter of the local input of end user.It also obtains the parameter by the CO indication.Then, it is according to the indicated calculating parameter of hereinafter.Modulator-demodulator uses the parameter after upgrading to communicate by letter with DSLAM.
The method that is used for setup of modulator-demodulator according to present embodiment is described now.This method allows modulator-demodulator dynamically to optimize some key parameters according to user preference.Modem performance is adjusted in the application of the expectation that it also provides according to operator or service.
Illustrated like Fig. 3, indicated like hereinafter, at step S1, modulator-demodulator at first receives parameter from CO.During modem configuration, at step S2, prompting user indication is used to use the following parameter of broadband connection:
The number of-the digit phone number that is associated with voice service,
The number of-the video channel that carries simultaneously through video flowing,
The type (SDTV or HDTV) of-the video channel sent,
-minimum destination service bit rate (if available).
If the end user does not know the minimum target service bit rate,, calculate it at DSL configuration module place according to following rule then at step S3:
The number * 100kbps of the digit phone number of-minimum destination service bit rate (voice)=be associated with voice service
-for SDTV, the number * 4000kbps of the video channel of minimum destination service bit rate (video)=carry simultaneously through video flowing,
-for HDTV, the number * 9000kbps of the video channel of minimum destination service bit rate (video)=carry simultaneously through video flowing,
Destination service bit rate (the video)+OAM of destination service bit rate (the voice)+minimum of destination service bit rate (the total)=minimum of-minimum connects bit rate (4kbps); Wherein OAM represents Operations, Administration and Maintenance.OAM connects bit rate and normally keeps the internet to connect required minimal bit rate.
The end user also has been given indication and has optimized the selection of type, so that optimize framing (framing) parameter.Particularly, given the selection of maximization stability or performance.Stability means with the cost optimization framing parameter of attainable bit rate to obtain to the possible maximum protection of unfixed noise.It is that cost attempts to realize possible maximum bit rate that performance means with the noise protection.Certainly, the end user can select to reconfigure the optimization type at any time.When revising the optimization type, carry out optimized Algorithm once more.
According to embodiment, indicate some parameters by the end user.Certainly, alternately, these parameters can be indicated to modulator-demodulator by ISP through any known Remote configuration agreement.This is with the participation that allows to carry out modem configuration and need not the end user.
This algorithm be based on some inputs of receiving from CO, from the user import derivation, or measure at modulator-demodulator.The input parameter that is used for optimized Algorithm is following:
-Min_INP is minimum Impulse Noise Protection.Its intention is to reduce the influence of impulsive noise to data.It uses the Reed Solomon Coding method to come application forward error correction (FEC).Min_INP is the input from CO.Minimum INP is used to guarantee the protection to the on-fixed noise.The big value of this parameter reflects the reduction of attainable Maximum Bit Rate.Actual_INP is the INP that is used for downstream direction of CPE selection and the INP that is used for updrift side that is selected by DSLAM.Because min_INP≤actual_INP freely selects the value of INP so be used for the CPE in downstream with the CO that is used for the upper reaches, usually as long as should constraint set up.Too conservative selection causes selecting than the lower bit rate of desired by services minimal bit rate that user or provider want to dispose for this parameter.
-Max_Delay is a maximum delay.Max_Delay is the input from CO.This parameter is provided with the degree of depth of interleaver function.The CPE that is used for downstream direction attempts Delay is provided with ground as much as possible near the Max_Delay parameter with the DSLAM that is used for updrift side usually.Such as VoIP some are used needs low the delay usually.
-Minimum_BitRate and Maximum_BitRate are the inputs from CO.They are used to calculate Actual BitRate (actual bit rate).They also are used to check when find that consequent new bit rate makes up with postponing without prejudice to the new INP of initial constraint: Minimum BitRate＜=Recomputed BitRate＜=Maximum BitRate.
-minimum destination service bit rate can be from service provider's communication and input that read or from the input that the end user provides, derive from the CPE configuration, and is indicated as hereinbefore.
Min_INP, Max_Delay, Minimum_BitRate, Maximum_BitRate are the parameters that in the CO profile, is provided with in the preparatory stage (provisioning phase).Their are communicated to modulator-demodulator according to about the ITU-T of the handshake routine that is used for Digital Subscriber Line (DSL) transceiver standard G.994.1 during Handshake Protocol.Actual bit rate be realize after the hand shaking and according to the data transmission rate of ADSL2 criterion calculation.As using of describing hereinbefore by user prompt video/voice.
In step S4, calculate Actual_INP and Actual_Delay then.If the user determines to optimize stability, then algorithm is attempted to maximize Actual_INP so that better to the Impulse Noise Protection video flowing.It also attempts to minimize Actual_Delay to reduce the service delay of the real-time application such as voice.If the user determines to optimize performance, then this algorithm is attempted to minimize Actual_INP so that restriction error correction expense.It also attempts to maximize Actual_Delay to guarantee the using interleaver memory that possibly reflect higher attainable Maximum Bit Rate better.Value after these upgrade is used through gateway, is used for utilizing DSLAM to carry out transfer of data at step S5.
The algorithm that is used to optimize stability is described now.
The 1st step: as at chapter 7.6, and more specifically in about the chapter 7.6.1 of the definition of deriving and chapter 7.6.2, stipulate about effective framing configuration about frame structure, according to CO profile and ITU-T standard G.992.3, modulator-demodulator calculating bit rate.This bit rate is the NET of the table 7.7 among the chapter 7.6.1
P.actThis delay is the delay of table 7.7
p
The 2nd step: target_min_INP=min_INP+1
Modulator-demodulator utilizes target_min_INP to recomputate to be used for the bit rate (Recomputed BitRates) of the min INP of domination (overrule) CO communication.This also causes and the new delay that interweaves (new Delay) that is fit to from the constraint of profile.
INP according to the indication of the table 7.7 among the chapter 7.6.1
pValue, calculate S as follows
p:
S
p＝2x(INPxN_FEC
p)/(D
pxR
pxDMTsymbols)
And use the formula of indication in the table 7.7 among the chapter 7.6.1, utilize S
pValue calculate NET
P.actAnd delay
pNew value.
The 3rd step: (making the maximized iterative cycles of INP):
New_Target_min_INP＝target_min_INP
While (Minimum_target_Service_Bitrate＜=Recomputed_BitRates＜=ActualBitRate) and (new_Delay＜=Max_Delay),
New_target_min_INP＝New_target_min_INP+1，
And modulator-demodulator calculates bit rate according to the New_target_min_INP value.This also causes showing and the new delay of calculating like the preceding text middle finger.
After the while circulation, the tabulation of sign Actual_INP value.Each Actual_INP value is superior to the min_INP of CO request.Each Actual_INP value and the Actual_Delay that wants and the new bit rate that recomputates that still satisfies Minimum_target_Service_Bitrate＜=Recomputed_BitRates＜=Actual BitRate constraint are associated.If at least one among the Actual_INP of the tabulation of being calculated＞=target_Min_INP, then this value becomes New_target_min_INP.If there is more than one, then chooses and cause the Actual_INP of the highest Actual_Delay.
The 4th step: (making the maximized iterative cycles of Delay):
Max_INP＝new_target_Min_INP
While (Minimum_target_Service_Bitrate＜=Recomputed_BitRate＜=ActualBitRate) (keep constant max_INP)
min_delay＝new_Delay-1
In this step, optimizing delay.For each new length of delay, obtain the new_target_min_INP value.And this new_target_min_INP value and target_min_INP value are inequality.Must check still establishment of initial constraint then: if (new_target_min_INP＞=target_Min_INP), then advance to next step.
The 5th step: export one group of new framing parameter Max_INP, min_Delay.It produces and still satisfies the new possible actual bit rate that CO is provided with the constraint that provides, and optimizes the protection to impulsive noise.
The algorithm that is used to optimize performance is described now.It is basically with the identical algorithm of algorithm that is used to optimize stability, below in this indication difference with it.
The 1st step: like preceding text indications, modulator-demodulator calculates bit rate.
The 2nd step:
2nd step: if Actual_INP＞Min_INP
target_min_INP＝ceil(Actual_INP-1)
If Actual_INP=min_INP then advances to step 4, otherwise
Modulator-demodulator recomputates the bit rate (Recomputed_BitRates) that is used to arrange the Actual_INP (as long as it still is higher than Min_INP) that utilizes new_target_INT and CO to consult.This also produces the tabulation of possible new delay (new_Delay) that interweave.In this indication, obtain these values like above algorithm.
The 3rd step (making the minimized iterative cycles of INP)
new_target_min_INP＝target_min_INP
While (Minimum_target_Service_Bitrate＜=Recomputed_BitRates＜=ActualBitRate) and (new_Delay＜=Max_Delay) and (new_Target_min_INP＞=min INP)
new_target_min_INP＝new_target_min_INP-1，
And modulator-demodulator recomputates bit rate according to the new_target_min_INP value.This produces new delay.
After the while circulation; The tabulation of the Actual_INP value (target_min_INP) that the modulator-demodulator sign is wanted, wherein each new bit rate that recomputates that has the new_Delay that wants and still satisfy Minimum_target_Service_Bitrate＜=Recomputed_BitRates＜=Actual BitRate constraint.
The 4th step: (making the maximized iterative cycles of Delay):
Min_INP＝new_target_Min_INP
While (Minimum_target_Service_Bitrate＜=Recomputed_BitRate＜=ActualBitRate) (keep constant Min_INP)
Max_delay＝new_Delay+ 1
The 5th step: export one group of new framing parameter Min_INP, max_Delay.It produces and still satisfies the new possible actual bit rate that CO is provided with the constraint that provides, and the highest actual bit rate is provided.
